Frisk is a blue-collar industrial farm employee. He's patriotic, and fiercely loyal to the empire. He was born as a mutant-anthropomorphic animal (Animalian) so he doesn't feel a need to sympathize with animalians who were born as normal animals. He looks down on them, and takes it personally when they break rank, or talk of the empire's flaws. 

His voice claim is "Satan" from "Helluva boss", or "Amaroq" from "No evil"
